Re: Processing files in a directory
Doing what you propose is possible, but would take system resources and a bit tedious. Here's an alternate solution: From what I infer, you are processing on a file and then the code decides if its a success or a failure and your job is to remove tmp files if it fails. Here, when the processing code is done with its job, ask it to return an exit status (say return1 for success and 0 for failure). Then based on this return status, you can do your job. If itsn't clear, get back -susheel On Tue, Nov 11, 2008 at 6:18 AM, satish km [EMAIL PROTECTED] wrote: Hi, My requirement is like this: 1. There are 1000 files in a directory(DIR1) 2. When processing is started, ex file1 wil be converted to temp_file1, then processed and both file1 + temp_file1 are removed from DIR1 within 2-3 seconds. if any temp_file* (ex: temp_file6) is still present in DIR1 means processing failed. So I need to periodically check in if any temp_file* generated is staying for more than 30 seconds (which means processing failed), then I hv to move this temp_file* to some other folder and restart processing again of the remaining files. I am trying to achieve this using perl. Can u plz let me know how to achieve this. Thanks, Satish On Tue, Nov 11, 2008 at 5:11 AM, Susheel Koushik [EMAIL PROTECTED]wrote: use the PERL system command.

Re: Processing files in a directory
of course, there are many ways to do a job in perl. Its upto the implementer to choose. -Susheel On Mon, Nov 10, 2008 at 10:40 PM, John W.
